Tkinter: The button will jump up and down when I create a frame next to the frame which hold the button

The 4 button is at the top left corning which using a frame named menuFrame to hold it. When the program started, it is staying at the correct position originally However. When I used the book search function, the button just went down to somewhere else.

I have totally no idea what is happening

I don't know is the way I used to change the page by different button leads to this unexpected result. The method I used is deleted the whole ItemFrame which hold all the things in the page and create a new one

At the same item, after I delete the frame using the .destroy function, the widget in the item frame cant go to the top level of the window.
